SMOKE-CONSUMING APPARATUS FOR LocoMoarIvE AND OTHER BOILERS.

Specification of Letters Patent.

Application filed'November 24,1914. Seria1'No.873,819.

7 '0 all whom it may concern:

Be it knownthat we, JOH E. PRICE, WIL- LIAM It. PRICE, and CHARLEsL. HILDRETH, citizens of the United States, of Covington, in the county of Kenton and State of Kentucky, have invented a certain new and useful Improvement in Smoke-Consuming Apparatus for Locomotive and otherBoilers, of which the following is a specification.

This invention relates to smoke-consuming devices that are used more especially in the outlet funnels or stacks of steam-boilers, and its object is to. provide a device concentrically within the smoke-stack of a locomotive-engine or the like, above the draftline, that will somewhat suspend or hold,

- in abeyance, the smoke in itspassage therethrough by means of a combined or lnter- 'mingled steam and air blast whereby the particles of carbon liberated from the firebox or furnace are given the desired supply of oxygen and consumed or-destroyed and not permitted to escape from the mouth or exit end of the stack into the surrounding,

atmosphere, and without detriment to the required draft in the stack but, on the other hand, to somewhat improve it at no material sacrifice of economy.

The features of the invention will be fully hereinafter described and then particularly defined in the claim that follows- In the accompanying sheet of drawings,

Figure 1 is a plan view of our device showing it in position in a fragmentary portion of the fore end of a locomotive-engine; Fig. 2, an elevation of the same but with part of the stack broken open and in section to more clearly show the internal steam-ring and,

distributing air and steam nozzle structure; and Fig. 3, a detail sectional view taken on the line a, a, of Fig. 1 and showing a fragment of the said internal steam-ring and one of the exit steam nozzles or spray de} vices thereof.

1 indicates the fore end of a locomotiveboiler having the customary stack-saddle 2 and the upright stack or funnel 3 the latter being of any suitable height and diameter and above the draft-line, as customary.

at is a horizontal, hollow ring suitably supported within the stack at the end of a steam supply-pipe 5 that leads to a steamsource-control in the cab of the engine. This ring has a series of perforated nozzles or and residents spray devices6 carried by radial upwardlydisposed tubes 7 that proj ect; inwardly there,- from, as best seen in Fig. 3; In Fig. 1 we have shown sixof these spray-nozzles, but it is obvious that a greater or less number may be employed to suit conditions. These steamspray nozzles or diffusers may also be of other than the spherical form.

PatenteclNov. 2 1 915.

"8 indicates each one of a pair of air-re-Q 1 ceptacles, each'one carryingat its opposite ends a jet-tube 9 that extends through the Waller shell of'the stack into its interior directly beneath the said steam-ring 4:, as seen in Figs. 1 and 2. These jet-tubes each carry a perforated head or nozzle 10 that diffuses the air from the receptacles 8 that, in turn, get their supply under pressure through the pipes 11 that lead to the aircollecting devices on the engine-cab where they are held under due control. p

The air-supply) pipes 11 are each furnished with exit nozzles orjets 12 (shown in dotted-lines in Fig. 2) that are mounted in the lower pendent ends 13- of the air-receptaclesS (Fig. 2) and are of smaller (ll-1' ameter'than the bore of the said ends 13 so as to provide for an air-inlet from the sur-' rounding atmosphere to augment theflow of air and oxygen to the exit-nozzles 10 that are preferably located on the same horizontal plane as that of the steam-nozzles 6 and lie adjacent the latter, as best seen in Fig. 1. In operation, the air issuing from the nozzles 1Q mingles with the dry steam passing under duly controlled pressure from the nozzles 6. and is duly heated thereby, which, together with the flame or high degree of heat that passes through the boiler fines or tubes from the fire-box, is sufficient to con-' sume or burn the particles of carbon or soot that are ordinarily liberated from the furnace in the operation of the locomotive or other steam boiler in connection withwhich our device is applicable. i

The device is preferably but not essentially arrangedat the middle of the stack, but it can beplaced at any point above the draft-line that lies below the saddle 2.

e claim In a smoke-consuming apparatus for 10 comotive and other steam boilers, the combination of an exit stack or funnel, a horizontal, circular, steam-chamber or hollow steamring having a plurality of radial, upwardlydisposed steam spray-nozzles and mounted concentrically Within said stack on a plane chamber from a controlled-source, a pair of horizontal semi circular a1r receptacles mounted opposite each other outslde the stack With the latter intervening and having" at their opposite ends, radial, upwardlyclisposed spray-nozzles that extend through punctures made in the cylindrical shell of the stack above said draft-line and are spray-nozzles, and air pumping conductors leading to said pair of semi-circular air-receptacles from a controlled source.
